Challenge
A long-winded title
Only rule: the title itself must be longer than the actual writing. [If Prose still forces the 15-word minimum, you can bold the title and make it part of the body of the text, or place a bracketed nonsense filibuster at the bottom.]
I accidentally wrote the entire email in the subject line and nobody told me, now everyone in the office judges my terrible emailing skills
At least I don't send chain emails, except for that one time in the 4th grade...
